Description of the Invention: [Technical Field] The present invention relates to a technique for recording data to an optical storage medium, and more particularly to at least one method of recording data to an optical storage medium and a light@storage device. [Prior Art] Optical storage media, such as rewritable compact discs, have become popular data carriers. Usually, the old material 1 stored on the rewritable disc is overwritten by the new material when it is written again. In particular, certain areas on a rewritable disc can be overwritten frequently. For example, the Direct Over-Write (DOW) method is mostly used for the Recording Management Data (RMD) of a DVD-RW disk, and the Formatting Disk Control of a DVD+RW disk. Block, FDCB), BD-RE/DVD-RAM disk defect management area (Defect Management
Area，DMA)及檔案結構(file structure)。通常，對於頻繁覆寫 的區域，覆寫前的舊的資料内容與用於覆寫的新的資料内容有 可能彼此相似。執行過多次資料覆寫後的區域的可讀性有可能 會比較弱，導致可重寫式光碟的使用壽命縮短。 此外，即便舊的資料内容與新的資料内容不同，相同的頻 201113878 繁覆寫區域的區段識別碼（簡稱區段ID)是相同的。資料^ 寫區域的區段w的可m性有可能比較弱，因而影響到儲存在 -由該區段ID所識別的區域中的使用者資料的存取。 為了延長可用的DOW循環使用壽命，傳統技術採用調整 寫入功率或祠服參數（如閉迴路增益）的方式。然而，由於^ 碟/光碟驅動機的固有變量，傳統技術難以將任意可重寫式光 碟的可用的DOW循環使用壽命保持在可接受位準(acce^abie 春level)之上。 【發明内容】 =於此，树明提供至少—種„料賴域學儲存媒 體的方法及光學儲存裝置。 含.在本供—種將㈣記錄至光學儲存媒體的方法，包 3 ·在將㈣⑽光學儲存媒體上㈣望 學儲存媒體之前，根據對應於該期望鏈接點的2 :條件，設置對應於該期望鏈接點的目前二 ★峨铸’控制將資料記錄至該光學儲存媒體的操作。 包含^^^__光學儲存媒體的方法， 先干儲存媒體之前，產生對應於該期望鏈接=己=: 201113878 (1 andom number)，並根據該隨機數設置對應於該期望鏈接點的 目别己綠條件，以及根據該目前記錄條件，控制將資料記錄至 ύ亥光學储存媒體的操作。 本發明另提供一種將資料記錄至光學儲存媒體的方法， 包含：在將資料從該光學儲存媒體上的期望鏈接點起記錄至該 光學储存媒體之前’從預設順序序列中導出對應於該期望鏈接 二的順序序列數（sequential sequence number)，並根據該順序序 列數設置對應於該期望鏈接點的目前記錄條件；以及根據該目 别u己祿條件，控制將資料記錄至該光學儲存媒體的操作。 、本發明另提供一種光學儲存裝置，用於將資料記錄至光導 f存媒’邊光學儲存裝置包含：驅動區塊，用於驅動光學 資料記錄操作；儲存單元，儲存對應於該光學儲抑 :的至卜期望鏈接點的至少—減前 益，耦接於該驅動區掄血吁处士 媒體上的期望鏈存單元，在將資料從該光學_ 鍵接起s己錄至該光學儲存媒 根據對應於該㈣鏈接_5/千邮魏、，_理署 fJs ^ «Η ^ ‘的至夕—個先前記錄條件，1署斟Μ t;望鏈接點的目前記錄條件，以及該處理器根據:二 學儲存媒體。 “㈣光學讀寫鄉㈣記錄至幻 資料記錄至光學 用於驅動光學讀 201113878 寫頭實現資料記錄操作；儲存單元，儲存對應於該光學儲存媒 體上的至少一期望鏈接點的隨機數；以及處理器，耦接於該驅 動區塊與該儲存單元，在將資料從該光學儲存媒體上的期望鏈 接點起記錄至該光學儲存媒體之前，該處理器產生對應於該期 望鏈接點的隨機數，並根據該隨機數設置對應於該期望鏈接點 的目前記錄條件，以及該處理器根據該目前記錄條件，控制該 驅動區塊驅動該光學讀寫頭將資料記錄至該光學儲存媒體。 本發明另提供一種光學儲存裝置，用於將資料記錄至光學 儲存媒體，該光學儲存裝置包含：驅動區塊，用於驅動光學讀 寫頭實現資料記錄操作；儲存單元，儲存查對應於該光學儲存 媒體上的至少一期望鏈接點的預設順序序列；以及處理器，耦 接於該驅動區塊與該儲存單元，在將資料從該光學儲存媒體上 的期望鏈接點起記錄至該光學儲存媒體之前，該處理器從預設 順序序列中導出對應於該期望鏈接點的順序序列數，並根據該 順序序列數設置對應於該期望鏈接點的目前記錄條件，以及該 處理器根據該目前記錄條件，控制該驅動區塊驅動該光學讀寫 頭將資料記錄至該光學儲存媒體。 利用本發明所提供的至少一種將資料記錄至光學儲存媒 體的方法及光學儲存裝置，與傳統技術相比，其優點之一在於 可以延長可用的DOW循環使用壽命。 201113878 以下係根據多個圖式對本發明的較佳實施例進行詳細描 述，本領域習知技藝者_後應可明確了解本發明的目的。 【賁施方式】 在說明書及申請專利範圍當中使用了某些詞彙來指稱特 疋的組件。所屬領域中具有通常知識者應可理解，硬體製造商 可能會用不同的名詞來稱呼同一個組件。本說明書及申請專利 视囡亚不以名稱的差異來作為區分組件的方式，而是以組件在 功能上的差異來作為區分的準則。在通篇說明書及申請專利範 固首中所提及的「包含」為一開放式的用語，故應解釋成「包 d 在可接受的誤差範圍内’所屬領 ;者能夠在4誤差範圍内解決所述技術問 々，基本達到所述技術效果。此外，「轉接」一詞在此包含任 何直接及間接的電性連接手段。因此，若文中描述-第一裝置 相第二裝置，則代表該第一裝置可直接電性連接於該第 -故置’或透過其他裝置錢接手段間接地電性連接至續第二 裝置。說明書後續描述為實施本發日㈣㈣實施 时 本發明的-般原則為目的，並非用以限定本發二 本Μ的保護範圍當視所附的申請專利範圍所界定者為 201113878 儲存媒體的相同位置上寫入相同資料内容的次數為目的。換言 之’原則上，在相同的鏈接點（link point)(例如，相同的記錄 - 起始位址）處，避免目前記錄條件與先前記錄條件相同的情況 • 發生。簡言之，根據本發明一實施例的將資料記錄至光學儲存 媒體的方法包含：在將資料記錄至光學儲存媒體之前，根據對 應於期望鏈接點（eXpected link point)的至少一個先前記錄條件 設置目前記錄條件’並根據目前記錄條件將資料記錄至光學饨 存媒體。根據本發明的一個較佳實施例，目前記錄條件與上述 春至少一個先則條件中的每一者均包含部分資訊，該部分資气與 初始調變資料型樣(data pattern)、記錄起始位址的偏移位元數 目、調變資料長度調整量或上述三者的任意組合有關，其中 初始調變資料型樣可例如初始8_14調變（Eight-to-F^n Modulation ’ EFM)型樣。對於本實施例的進一步說明細述如下 第1圖為根據本發明一實施例的光學儲存裝置的區塊八立 圖。光學儲存裝置（例如，光碟驅動機）1〇〇包含轉輔… (spindle motor)l〇2、光學讀寫頭1〇4、耦接於光學讀寫頭馬達 的驅動區塊106、耦接於驅動區塊1〇6的控制器1〇 、 及稱接於 控制器108的儲存單元11 〇。請注意，清楚簡潔 〜 一 ’、〜兄，第1圖 僅示出與資料記錄有關的組件，換言之，光學儲存裝置1〇〇 許具有合併於其中的額外的功能區塊。 允 201113878 102用於以所需轉速來旋轉光學儲存媒體(例 ‘存勺先碟）⑻°儲存單元UG為機器可讀媒體，可 儲存包含多條指令的韌體（firmwar 制器108執行以控制驅動區塊如2條才曰7可由控 例中的錯存單元no亦可儲存一=圖所示，在本實施 Γ ΤΓΓ 太K + J續（optional)的查找表Area, DMA) and file structure. In general, for areas that are frequently overwritten, the old material content before overwriting and the new data content used for overwriting may be similar to each other. The readability of the area after repeated data overwriting may be weak, resulting in a shortened life of the rewritable disc. In addition, even if the old data content is different from the new data content, the section ID (referred to as the section ID) of the same frequency 201113878 is the same. The m of the data w of the write area may be weak, thus affecting the access of the user data stored in the area identified by the section ID. In order to extend the useful life of the DOW cycle, conventional techniques employ a method of adjusting the write power or the feed parameters (such as closed loop gain). However, due to the inherent variables of the disc/disc drive, conventional techniques have difficulty maintaining the usable DOW cycle life of any rewritable disc above an acceptable level (acce^abie spring level).

If there is a previous record condition, go to the step; otherwise, go to step 214. If yes, step: read the previous record condition from the lookup table. 208: Set the pre-recording condition according to the previous recording condition, and according to the current &, heart, and the point of the link point to step 218, step 214, step 216, step 218, condition, ... conditional update, lookup table 1, after processing, Second should be in the period The initial recording condition of the link point is stored. The initial recording condition is stored in the lookup table. Condition. The current record from the lookup table into the corresponding _wang key contact step 220: according to the operation of the current storage media. To optical storage step 222: End. One of the concepts of the present invention is that the storage medium (8) cuts the desired content to the desired link point (for example, the optical record is different from the current record). % corresponds to the previous record condition of the different desired link points of the same desired link point. In addition, the storage unit shown in FIG. 1 is stored in the lookup table (for example, if necessary, the optional lookup in the case of caution) In the table LUT), therefore, the money material (4) is recorded to the optical 201113878 storage medium (8), according to the method of storing the medium, before recording the data to the optical medium according to the embodiment, first in Xiang find: 妾 point to actually record the data to at least one of the previous record strips of the optical storage point; (step search corresponds to the desired record in the case of the case, the previous record conditions that can not be contacted ^ (4) corresponds to the period Before the link point is written into the optical storage medium, there is no data. After the recording condition of the desired link book can meet the specifications of the optical storage medium 1G1, the initial recording condition is stored in the initial recording condition, and then step 214 and step 216). - Find the entry of the table LUT (step in step 204, when found in # LUT, tone.:, the previous record condition of the north link point can be found in the lookup table optical storage media ii It has been written from the desired link point to the optical storage. Therefore, 'According to the data of the current application, the condition is determined to determine the method. The previous record embodiment command can be read from the lookup table LUT. The current recording conditions for the desired key contacts. The current recording condition at - a preferred previous recording condition = desired link point is set to avoid the lifetime. More m secrets 5, ♦ thus effectively extending the available D0W loops used according to the previous record lookup table in the LUT after exporting the previous record conditions, and when deciding: *Surpose the current record record corresponding to the desired link point The condition update 杳 'the recorded condition is different from the previous recording condition, according to the current lookup table LUT (steps 206 and 208). After the current 201113878 recording condition is stored in the lookup table LUT, the current recording condition corresponding to the desired link point can be derived from the lookup table LUT, if necessary, and the data can be recorded to the optical storage medium 101 according to the current recording conditions ( Step 218 and step 220). If the same goal can be achieved, additional steps can be added to the flowchart as shown in Figure 2. For example, when no previous recording condition corresponding to the desired link point is found in the lookup table LUT, meaning that no material has previously been called to write to the optical storage medium 101 from the desired link point, according to another embodiment of the present invention, The available free storage space in the lookup table LUT can be detected before step 214 is performed. When the lookup table LUT is not full, step 214 is performed. However, if there is not enough free storage space in the current lookup table LUT, the existing items in the lookup table LUT can be removed, thereby generating enough free storage space to record the desired feed. According to an embodiment of the present invention, for one or more link points in which the respective recording conditions are stored in the lookup table LUT, the link point with the least frequently used data record is selected, and the lookup table LUT is stored in the An item corresponding to the recording condition of the selected link point. For example, each item in the lookup table LUT is associated with an update count value that is used to record the number of times the item has been updated by the record condition corresponding to the corresponding link point. In other words, each time the item of the corresponding lookup table is updated, the update count value changes by one unit quantity (for example, plus one). Therefore, the item to be removed can be easily identified by detecting the update count value of all items of 201113878 included in the lookup table LUT. Please note that the method of using the update count value to identify the item to be removed in the lookup table is only used for the purpose of the 5 brothers. The present invention is not limited thereto, and any identifiable storage link having a frequency of use is less. The manner of corresponding recording conditions falls on the protection of the present invention. For the second step, the generation of the recording conditions depends on the specification of the optical storage (8). For example, when the optical storage medium 101 listens to one of the disk, the Teng + RW disk, the D.

More (starting from (4) (4) is the plane of the disaster monitoring, the initial modulation data type is the letter of the pit and the initial modulation data type is flat. The c-wave animal optical storage medium 101 is a DVD_RAM magnetic book, and an accurate link point (for example, at 2 o'clock, according to the disc specification c, for example, a 6-recorded start address) and a desired link point 14 201113878 (for example, expectation The recording start address is the same. However, the initial modulation data pattern (for example, the initial 8-14 modulation data pattern) may be a pit or a plane as shown in Fig. 4. In addition, according to the DVD-RAM disk In the specification, the length of the modulated data is adjustable. Figure 5 is a schematic diagram of the length of the modulated data in a certain area. As shown in Figure 5, the length of the modulated data in a certain area is not mosquitoes. The modulation data length adjustment amount (including length j and length κ) can be set randomly. Therefore, for the capital The recording condition recorded to the DVD-RAM disk, via the appropriate setting of the initial modulation data pattern (initial pit/plane), and/or the gap area (cafid/buffer area) as shown in Fig. 5 (Buffer) The length in fldd); and the length κ in the protected area (Gardl/Gard2), the recording conditions can be dynamically changed. In view of this, when the optical storage medium 1〇1 is a CD-RW disk, a D VD+RW disk, When one of the D VD_RW disk and the bd_re disk, the above-mentioned current recording condition corresponding to the period (four) contact and the previous recording condition may be changed by the initial view (four) pattern and/or the offset position of the recording start position. (The number of shlft (four) is configured to be different. In addition, when the optical storage medium 101 is a two-disk, the above-mentioned current recording condition and month" conditions corresponding to the desired link point can be changed by the initial modulation data type and The amount of adjustment is configured to be different. Wenbei shake length 201113878 Fig. 6 is a detailed flowchart of the first embodiment of step 208 shown in Fig. 2. If the results are substantially the same, the execution steps need not be strictly as shown in Fig. 6. The order shown is performed in sequence. Step 208 The first embodiment comprises the following steps: Step 602: Generate a random number corresponding to a desired link point, or derive a sequence number corresponding to the desired link point from the preset sequence sequence. Step 604 · According to the random number / The number of sequential sequences sets the number of offset bits of the recording start address. Step 606: Compare the number of offset bits of the recording start address between the current recording condition and the previous recording condition. Step 608: Corresponding to the current recording condition Is the number of offset bits of the record start address allowed? If so, go to step 610; otherwise, go to step 602. Step 610: Store information related to the current recording condition, the number of offset bits of the recording start address, into the lookup table item, where the lookup table item is used to store the current recording condition corresponding to the desired link point. Information. Step 612: Generate a random number corresponding to the desired link point, or derive a sequence number corresponding to the desired link point from the preset sequence of sequences. Step 614: Set an initial modulation data type according to the random number/sequence sequence number (for example, an initial 8-14 modulation data pattern). Step 616: Compare the initial modulation data pattern between the current recording condition and the previous recording condition. Step 618: Is the initial modulation data type of the current recording condition allowed? If yes, go to step 620; otherwise, go to step 612. 16 201113878 Step 620: Store information related to the initial modulation data pattern corresponding to the current recording condition into the above lookup table item. In short, the step of setting the current recording condition (including the preliminary recording condition) corresponding to the desired link point may include: preliminary recording conditions (possibly including the recording start address and/or the initial modulation data type) The number of offset bits is compared with the previous recording condition corresponding to the desired link point to generate a comparison result, and the current recording condition is determined according to the preliminary recording condition and the comparison result, where the comparison result shows the preliminary recording condition and When the previous recording conditions are different, the preliminary recording condition is set to the current recording condition. Otherwise, the preliminary recording conditions are adjusted until the comparison result indicates that the preliminary recording condition is different from the previous recording condition, and then the adjusted preliminary recording condition is set as the current recording condition. For example, when the number of offset bits of the recording start address and the initial modulation material type are different from the previous recording conditions, the preliminary recording condition is set to the current $ recording condition. Please note that the examples are for illustrative purposes only, and the invention is not limited thereto. Further, for the setting of the current recording condition corresponding to the desired link point, the random number or the sequence number of the sequence may be generated according to at least one previous recording condition in the lookup table corresponding to the desired link point, and the random number or the sequence number of the sequence The method of production is not limited to this. The random number or sequence number can be used to determine how to set the number of offset bits for the record start address and the initial modulation data type. For example, a random number can be mapped to a particular setting of the number of offset bits at the beginning of the record; 17 201113878 Similarly, a random number can also be mapped to a particular setting of the initial modulation data pattern. The pre-set sequence consists of a number of sequential sequence numbers arranged in sequence. The number of sequential sequences derived from the first predetermined sequential sequence can be mapped to a particular setting of the number of offset bits of the recording start address. Similarly, the number of sequential sequences derived from the second predetermined sequential sequence can also be mapped to a particular setting of the initial modulated data pattern. Note that the first-predetermined sequential sequence and the second preset sequential sequence may be the same or the same, depending on the actual design requirements. In the flowchart shown in FIG. 6, step 61 and steps are performed to update the lookup table LUT according to the current recording condition corresponding to the desired key contact, wherein the condition record includes partial information, Part of the information is related to the record start address 2 offset bit number and the initial modulation data type. For the poor news related to the number of records of the starting address, the part of the recorded information may indicate the exact link = the continuous recording start address) and the reference point on the optical storage medium 1Qi (dlsplaeement) ' For example, it is expected that the wobble before the link point (four) = address), the wobble address after the link point is expected (real 4 expects the link point itself. The number of offset bits with two St start addresses and the initial modulation data type meter In the middle, the respective setting results are directly obtained. In the other setting, the current recording condition including the == desired link point is updated to find the actual number of the reference:: Recording conditions are recorded to the optical storage medium of the data, conditions, and The actual recording conditions corresponding to the desired duty are stored in the 18 201113878 lookup table. In other words, 'when the data is recorded to the optical medium an according to the current recording conditions, the deviation from the recording start address can be obtained via the execution-measurement step- Information on the number of shifting elements and the initial modulation data pattern. The above embodiments are within the scope of the present invention. Please note that based on actual design considerations, steps (10) and 62.

However, this is only used to illustrate the invention. In this alternative design, each of the current recording conditions and the monthly recording conditions is defined as including the initial modulation data type information, and step 602 1 step 61 as shown in FIG. 〇 can be omitted. ^ In another design, each of the current recording conditions and the previous recording conditions is the information related to the reading of the offset bit of the recording start address, and 〇 Figure 6 The steps 612 to 62 can be omitted. Figure 7 is a detailed flow of the second embodiment of the second embodiment shown in Fig. 2, and the right result is substantially the same, and the execution steps need not be strictly as shown in Fig. 7. Execute in order The second embodiment of step 208 comprises the following steps: 19 201113878 Red Γ = generating a - random number corresponding to the desired link point, or deriving from the preset sequence sequence corresponding to the expected _ trace.

Step 714: According to the random number/sample (for example, the initial (four) heart-to-be-modulated data type modulation is compared with whether the initial permission between the current recording condition and the previous recording condition is allowed to be transferred to step 720. Otherwise, go to step 712. About St: The current recording condition and the initial modulation data type are stored in the above lookup table item. 20 201113878 For example, the first sound of step 208 a The case of the disc; == optical storage _ in the case where the optical storage medium 101 is one of a CD_RW disk, a 〇-- a poor application for one of D:-RW disk and ·RE disk. Two::: second The embodiment is similar to the palladium case illustrated in Fig. 6, except that each of the previous recording conditions of the second embodiment of the step contains the variable data length 2 and the material type instead of recording. The offset of the starting address is in the shape of the second-behicle material. Therefore, according to the above-mentioned first embodiment of the step 2〇8, the person skilled in the art (4) can easily understand, when the tune is long.

In addition, in Figure 7 The illustrated flow chart carrying step (4) is based on the current record=row corresponding to the desired link point, and the alpha update is used to hide the LUT, wherein, in the present embodiment, the current condition 2 includes and the "feed length adjustment amount and Initial modulation data type information. Please note that 'the information with the modulation data length adjustment and the initial modulation f type = off can also be directly obtained through the information of the respective setting results. However,: - design towel 'decrease At present, the recording conditions are recorded in the optical storage II 101, which is related to the adjustment of the length of the modulated data and the initial modulation data: 21 201113878 The amount of adjustment of the length of the material can be adjusted and the initial acquisition.

In another design towel, each of the current recording conditions and the previous recording conditions is defined as including information related to the initial modulated data type. And step 7〇2 to step 71〇 as shown in Fig. 7 may be omitted. In another design, each of the recorded conditions and the previously recorded conditions may be defined as containing and modifying the feed. The information relating to the length adjustment amount and the step as shown in Fig. 7 can be omitted. In the above embodiment, the preliminary recording conditions set based on the number of random number/sequence sequences are compared with the previous recording conditions derived from the lookup table to determine whether the initial recording condition is suitable as the current recording condition. However, it is also feasible to compare the preliminary recording conditions corresponding to the same desired link point with the stored one or more previous recording conditions, and fall within the scope of the present invention. For example, when the preliminary recording condition is different from one or more previous recording conditions 4 derived from the lookup table, the preliminary recording condition configured according to the random number/sequence sequence number is set to the current recording condition required by 22 201113878, where each The recording conditions include partial information, and the partial information is related to the initial modulation material type, the offset number of the initial position, the modulation data length adjustment amount, or any combination of the above. The comparison of the preliminary recording conditions with the at least one previous recording condition as described above is to ensure that the current recording conditions obtained according to the appropriate preliminary recording conditions are different from the previous recording conditions, thereby achieving the best improvement in the D0W cycle life. However, in the case where the current recording condition is directly set via the number corresponding to each: number/sequence sequence without the comparison step 2 of the above application, the lifetime of the available D0W cycle can also be used via this recording condition setting mechanism. increase.
